The Qixia Formation in the Tonglu area of Zhejiang Province can be divided into two fusulinid biozones:the upper Cancellina neoschwagerinoides-Verbeekina grabaui zone of the Xiangbo Stage and the lower Misellina claudiae zone of the Luodian Stage.The Qixia Formation includes three 3rd-order sequences and six 4th-order sequences.On the basis of sedimentary cycles of the Qixia Formation,three depositional facies can be recognized:platform facies, shallow sea continental shelf facies and basinal facies. The Qixia Formation records a deepening upward sequence,shifting from platform to basin facies.
